Behavioral paradigm.

Note. Upper panel: Timeline of one example trial. The cue instructs the participant to draw a circle, while the partner will draw a diamond. The shapes are executed after the starting point turns green. Bottom left panel: Congruency manipulation. Depending on the combination of shapes drawn by the participant and the partner, trials could be congruent or incongruent. Bottom right panel: Social context manipulation. Participants carried out a Joint and a Parallel task, requiring to synchronize the drawing time with the partner or to draw consistently in 2 s, respectively.
